S3 Outage Highlights Fragility of Web Services

Source: http://feeds.feedburner.com/~r/OmMalik/~3/341132517/

Amazon’s S3 cloud storage service went offline this morning for an extended period of time — the second big outage at the service this year. In February, Amazon suffered a major outage that knocked many of its customers offline.

It was no different this time around. I first learned about today’s outage when avatars and photos (stored on S3) used by Twinkle, a Twitter-client for iPhone, vanished.

My big hope was that it would come back soon, but popular S3 clients such as SmugMug were offline for more than eight hours — an awfully long time for Amazon’s Web Services division to bring back the service. As our sister blog, WebWorkerDaily, points out:

With two relatively serious outages in the space of 6 months, some will be asking the question of why depend on S3? The answer is simple: the rates are hard to beat, especially for service that doesn't require any sysadmin budget.

That said, the outage shows that cloud computing still has a long road ahead when it comes to reliability. NASDAQ, Activision, Business Objects and Hasbro are some of the large companies using Amazon’s S3 Web Services. But even as cloud computing starts to gain traction with companies like these and most of our business and communication activities are shifting online, web services are still fragile, in part because we are still using technologies built for a much less strenuous web.

Update: Antonio Rodrigez, founder of Tabblo, now part of HP, on his blog asks the $64,000 pertinent question:

…if AWS is using Amazon.com’s excess capacity, why has S3 been down for most of the day, rendering most of the profile images and other assets of Web 2.0 tapestry completely inaccessible while at the same time I can’t manage to find even a single 404 on Amazon.com? Wouldn’t they be using the same infrastructure for their store that they sell to the rest of us?

Update #2: Building an offline redundancy for Amazon S3 could be big opportunity, Dave Winer says.

Update #3: A reader sent me an email and asked these two questions

  • Is the system designed to be fault tolerant? If yes, then how did it go down? After all they must have massive arrays and mirrors of their storage infrastructure.
  • Is this a hardware failure or a software/design problem?

Random Thought: The S3 outage points to a bigger (and a larger) issue: the cloud has many points of failure - routers crashing, cable getting accidentally cut, load balancers getting misconfigured, or simply bad code.

QuickSend Sends Simple, One-Hand Emails from Your iPhone [Featured IPhone Download]

Source: http://feeds.gawker.com/~r/lifehacker/full/~3/339343820/quicksend-sends-simple-one+hand-emails-from-your-iphone

quicksend.pngiPhone/iPod touch only: Free application QuickSend creates and sends simple emails in a flash through a one-hand-friendly interface. When you fire up the app, you get two scrollable sections: the first with email addresses of your contacts and the second with messages. Line up the two you want and tap the Email It button. QuickSend launches a new email with the necessary fields auto-populated, and all you have to do is hit send. While it's a great app for one-handed emails, it could use some improvements. First, if you've got a lot of contacts, finding the right address in the unsorted list is a pain. Second, this really seems best suited for an SMS-integrated application, since these are the sorts of messages you want to send when someone isn't necessarily at their computer. Either way it's a good start. QuickSend is freeware, requires an iPhone or iPod touch running 2.0 firmware.

Take Psychedelic Pictures with Your iPhone [IPhone]

Source: http://feeds.gawker.com/~r/lifehacker/full/~3/340014547/take-psychedelic-pictures-with-your-iphone

-3.jpgWired's How-To Wiki demonstrates how to exploit the iPhone's unusual shutter to take distorted photographs. The trick? Just twist your camera as you're taking a picture.

The reason? The iPhone uses a CMOS sensor, which more or less "wipes" the shutter across the sensor like a scanner rather than the circular aperture of a traditional camera. The iPhone's CMOS scanner seems to be a bit slower than, say, the CMOS sensor on your Canon camera. Therefore, as the camera is recording the image, any changes over that small but significant amount of time are recorded.

Taking a psychedelic photo is actually just as easy as it sounds (works better in bright sunlight), but read on for a quick video demonstration.

If you've been checking out the newest VirtualBox beta for Mac OS X, or you're intrigued by Linux but not ready to deal with virtualizing it, the Sun xVM VirtualBox VDI Index—or, as it's skeevily nicknamed, veeDee-Eyes—has a host of pre-compiled, pre-configured images for you. No need to set up space, "boot" from a live CD and mess around with hardware config, as copies of Fedora, Ubuntu, OpenSUSE and others are ready to run. Not all of them are free, with a few of the multi-GB distros asking for a buck or two to cover server costs, but a good number of interesting variants and betas are there for the taking. VirtualBox runs on Windows, Mac, or Linux, and is a free download.
